Currently, a LCD manager's timings is set by dispc_mgr_set_lcd_timings() and TV
manager's timings is set by dispc_set_digit_size(). Use a common function called
dispc_mgr_set_timings() which sets timings for both type of managers.

We finally want the interface drivers to use an overlay manager function to
configure it's timings, having a common DISPC function would make things
cleaner.

For LCD managers, dispc_mgr_set_timings() sets LCD size and blanking values, for
TV manager, it sets only the TV size since blanking values don't exist for TV.

The RFBI driver uses dispc_mgr_set_lcd_size() to set the width and height of
the LCD manager. Replace this to use dispc_mgr_set_lcd_timings(), pass dummy
blanking parameters like done in the DSI driver.

This prevents the need to export dispc_mgr_set_lcd_size(), and use a common
function to set lcd timings.

Since any power on stabilisation delay for the supply itself should be
taken care of transparently by the regulator API when the regulator is
enabled the additional delay that the TPO-TD03MTEA1 driver adds after
that returned should be due to the requirements of the device itself
rather than the supply (the delay is also suspicously long for one for
a regulator to ramp). Correct the comment to avoid misleading people

The TAAL driver contains some regulator support which is currently unused
(the code is there but the one panel supported by the driver doesn't have
any regulators provided). This code mostly looks like an open coded
version of the regulator core bulk API.

The only additional feature is that a voltage range can be set once when
the device is opened, though this is never varied at runtime. The general
expectation is that if the device is not actively managing the voltage of
the device (eg, doing DVFS) then any configuration will be done using the
constraints rather than by drivers, saving them code and ensuring that
they work well with systems where the voltage is not configurable.

If systems are added needing regulator support this can be added back in,
though it should be based on core features rather than open coding things.

For some OMAP versions the TRM says that the pixel clock from DISPC can
be used as an input clock for DSI PLL, instead of the default, which is
sysclk.  For some OMAP versions the bits affecting this are marked as
reserved.  This feature has never been tested, so it's unknown if the HW
even works, and has never been used.

To clean things up, this patch removes the functionality. This should
not affect any board.

Most of the DSS clocks have restrictions on their frequency based on the
OPP in use. For example, maximum frequency for a clock may be 180MHz in
OPP100, but 90MHz in OPP50. This means that when a high enough pixel
clock or function clock is required, we need to use OPP100.

However, there's currently no way in the PM framework to make that kind
of request. The closest we get is to ask for very high bus throughput
from the PM framework, which should effectively force OPP100.

This patch is a simple version for handling the problem. Instead of
asking for OPP100 only when needed, this patch asks for OPP100 whenever
DSS is active. This obviously is not an optimal solution for cases with
small displays where OPP50 would work just fine. However, a proper
solution is a complex one, and this patch is a short term solution for
the problem.

Commit c79396c1 ("mmc: sdhci: prevent card detection activity
for non-removable cards") disables card detection where the cards
are marked as non-removable.

This makes sense, but the implementation detail of calling
mmc_card_is_removable() causes some problems, because
mmc_card_is_removable() is overloaded with CONFIG_MMC_UNSAFE_RESUME
semantics.

In the OLPC XO case, we need CONFIG_MMC_UNSAFE_RESUME because our root
filesystem is stored on SD, but we also have external SD card slots
where we want automatic card detection.

Refine the check to only apply to hosts marked as MMC_CAP_NONREMOVABLE,
which is defined to mean that the card is *really* nonremovable. This
could be revisited in future if we find a way to improve
CONFIG_MMC_UNSAFE_RESUME semantics.

This continues the theme started with vm_brk() and vm_munmap():
vm_mmap() does the same thing as do_mmap(), but additionally does the
required VM locking.

This uninlines (and rewrites it to be clearer) do_mmap(), which sadly
duplicates it in mm/mmap.c and mm/nommu.c.  But that way we don't have
to export our internal do_mmap_pgoff() function.

Some day we hopefully don't have to export do_mmap() either, if all
modular users can become the simpler vm_mmap() instead.  We're actually
very close to that already, with the notable exception of the (broken)
use in i810, and a couple of stragglers in binfmt_elf.

eMMC v4.5 discard operation is significantly different from the
existing trim operation because it is not guaranteed to work with
the new sanitize operation.  Consequently mmc_can_trim() is
separated from mmc_can_discard().

Also the new discard operation does not result in the sectors being
set to all-zeros, so discard_zeroes_data must not be set.

In addition, the new discard has the same timeout as trim, but from
v4.5 trim is defined to use the hc timeout.  The timeout calculation
is adjusted accordingly.
